Drainage waterproof membrane black roll TERRAPLAST 1.5 x 20m

MASTERPLAST dimpled membranes are a special type of construction membrane covered with embossing in the shape of truncated cones (dimples).

This creates air gaps in the waterproofing layer to let water out.

They are installed as a waterproofing product, but they also facilitate the ventilation of the external foundation wall. Dimpled membranes offer long-lasting protection against mechanical damage.

They also protect the bituminous waterproofing coating against damage caused by foundation backfilling or building subsidence. The material is non-biodegradable and is resistant to the fungi, bacteria and chemical compounds present in the soil.
